lower

Definition: object x2 = lower(object x1)
Description: Convert an atom or sequence to lower case.

Should you need to, you can also invoke islower(integer ch) to determine if a character is lower case. [ASCII only]

Note that utf32_to_utf8(lower(utf8_to_utf32(utf8))) may be advised when dealing with utf8 strings, since lower(utf8) is likely to mangle individual bytes that are part of a multibye representation of unicode codepoints #100..#10FFFF. Nothing in that range is altered by lower().
pwa/p2js: Supported.
Example:
s = lower("Phix")
-- s is "phix"
a = lower('B')
-- a is 'b'
s = lower({"Phix", "Programming"})
-- s is {"phix", "programming"}
Implementation: See builtins\pcase.e (an autoinclude) for details of the actual implementation.
